"Neither fondness for my son nor reverence for my aged sire nor the due love which ought to have gladdened Penelope could conquer in me the ardour which I had to become experienced in the world and in human vice and worth. I put out into the deep open sea with but one ship and with that small company which had not deserted me.... I and my companions were old and tardy when we came to that narrow pass where Hercules assigned his landmarks. 'O brothers,' I said, 'who through a hundred thousand dangers have reached the West deny not to this the brief vigil of your senses that remain, experience of the unpeopled world beyond the sun. Consider your origin, ye were not formed to live like Brutes but to follow virtue and knowledge.... Night already saw the other pole with all its stars and ours so low that it rose not from the ocean floor'"

('Inferno', xxvi., 94-126).
